FIELD

The present invention relates to a dispensing system generally, and in particular to a system for authorized dispense of medicines to an individual at pre-defined and pre-programmed time to ensure proper dosage of medicines, to prevent over dosage of medicines and the omission of prescribed medication, and drug abuse.

BACKGROUND

Medicines play a vital role in patients and healthcare industry. In the traditional system of medication, a physician looks into the symptoms of the illness in a patient and decides the kind, quality and the quantity of the medicine to be delivered to make the patient recuperate from the illness. The decision of the physician is communicated to a pharmacist in writing and the pharmacist holds the responsibility to dispense the right medicine comprising suitable medicinal formulation. The medicinal formulation included in a medicine may be either in the solid form that includes tablets, pills, finely granulated powders, injectable and the like or in the liquid form like syrups, and tonics or in gaseous form like sprays. Sometimes, the formulation may be a gel, paste or cream like ointments.

The delivery of right medicine to a particular illness depends on a plurality of factors. These factors include age, sex, weight, height and severity of illness, in addition to various other physical factors including blood pressure, sugar level in the body and in the blood. Sometimes, a medicine delivered for one kind of illness may be in severe contradiction to another kind of illness in the same patient.

Referring to the prior art, a study by American researchers shows that nearly seventy percent of Americans take prescription drugs, and more than half the US people receive at least two prescriptions. Twenty percent of US patients are found to be on five or more prescription medications. Among these prescriptions, antibiotics, antidepressants and painkiller opioids are the most common ones.

Expenditure on prescription drugs in the US accounts for more than for 12% of total personal health care expenditures. Many types of prescription drugs are abused. If a medicine is taken in a way that is different from what a physician has prescribed, then it is considered as prescription drug abuse. The prescription drug abuse may be due to any or all of the following reasons:

-   -   taking a medicine that was prescribed for someone else;     -   taking a larger dose of the prescribed medicine than prescribed         dosage;     -   taking the prescribed medicine in a way different from the way         as prescribed by the physician; and     -   using the prescribed medicine for another purpose.

Abusing some prescription drugs can lead to addiction including addiction to narcotic painkillers, sedatives, tranquilizers, and stimulants.

In US, it is estimated that nearly three fourth of prescription drug overdoses are caused by prescription painkillers alone. These prescription painkillers are also known as opioid pain relievers. Many people use prescription painkillers non-medically. Death due to the prescription drug overdoses is more than the deaths due to cocaine and heroin combined. Most of these drug overdose deaths are caused due to prescription drugs.

It has been observed that prescription drugs come from hospitals and emergency rooms, clinics, and pharmacies. Instead of meeting with a dealer, drugs could be made readily available by a physician by a simple prescription.

Nowadays, as more and more people are depending on medicines, manual dispensing of medicines has become a cumbersome task for pharmacists. In many cases, there is a risk of giving medicines without proper prescription by a physician. Hence, systems for dispensing medicines have been developed. The medicine dispensing systems available at present are bulky. It makes people unable to carry the dispensing system with them.

Further, in the aforementioned traditional medicine dispensing systems, there is no control over both the usage and misuse of medicines. Also, many of these aforementioned traditional systems are devoid of authorized dispensing of required medicines.

The United States patent application filed by Joseph Moloughney (Pompton Plaines, N.J., US), bearing the application Ser. No. 14/456,172 and publication No. US20160042150, and entitled ‘Intelligent Pill Dispenser With Remote Scheduling and Monitoring’, discloses a medication dispensing system with a remote app or a web page that allows an end user or a remote caregiver to create and change a dose per medication as well as a schedule for each medication dose.
